Engine Overview and Common Failures

The weight of the LLR engine assembly is 191 kg. The LLR engine number is located at the junction of the block and the gearbox. It is a reliable and durable unit, but its fuel consumption is not the lowest. On long distances, valve seat wear and chain elongation are often encountered. Many complaints are related to the low lifespan of the water pump and fan viscous coupling. It is important to monitor their condition, as aluminum engines do not tolerate overheating. Additionally, rear crankshaft seal leakage and exhaust manifold cracking are common issues here.
